What is a high power electronic load? What are the main areas of application? Where can I buy a good

The so-called high-power electronic load is only relatively speaking, high-power electronic load is only larger than the general electronic load, you first understand the concept of electronic load, electronic load is also called electronic load meter, is a kind of hardware used to simulate the electrical environment of other electrical equipment. Due to the simulation of the electricity environment, so it is a variable value, basically all the load is a programmable load (also called a programmable electronic load), because the power voltage and current under DC, and the algorithm of power in the AC environment is more complex, so the application and market are mostly direct process control electronic load!

What are the areas of application for electronic loads? In fact, the application field of electronic load is the same, as long as there is a need for electricity, it is possible to use electronic load, as small as the lithium battery in the watch, as large as the network power supply (storage group) of telecommunications, due to the different power, so the high-power electronic load is basically applied to the high-power power environment, such as: power battery, electric vehicle, charging pile, communication power supply, power system, etc.!

Where can I buy a good load? It depends on your use and price! Many people like foreign goods, and some people like copycat goods, if the accuracy and function are not used much, the cottage can basically meet the demand.

Now there are several major load brands on the market: Advics, Festech, Zhimao, Boji, Meiernuo, etc., you can go to various official websites to see and consult, it seems that FT6800A has sprung up in the market recently, and it sells well.

High-power electronic loads and low-power loads are basically the same except for the discharge power, which is basically a resistive load, which is equivalent to installing an electrical load in the circuit, such as a high-power or low-power load such as a lamp, an electric motor, an electric kettle, and a hot iron. It is mainly used to detect whether the power supply or testing performance of the power supply or testing equipment meets the requirements and whether it can ensure the safety of electricity after the power supply or testing equipment manufacturing enterprise manufactures the power supply or testing equipment. There are basically electrons everywhere, or you can search for high-power loads.

The so-called high bai power electron negative.

Du load is only relatively speaking, and high power electric load is only more power than general electron.

The load version wants a lot of power.

The concept of electronic load, also known as electronic load meter, is a kind of hardware used to simulate the electrical environment of other electrical equipment. Because of the simulated power environment, it is indefinite, and basically all loads are programmable loads (also called programmable electronic loads).

Due to the power voltage and current under DC, and the algorithm of power in AC environment is more complex, so the application and market are mostly direct flow control electronic loads!

What are the areas of application for electronic loads? In fact, the application field is the same as that of electronic loads, as long as there is a need for electricity, electronic loads may be used, as small as lithium batteries in watches, and as large as telecommunications network power supplies (energy storage groups).

Due to the different powers, high-power electronic loads are basically applied to high-power power environments, such as: power batteries, electric vehicles, charging piles, communication power supplies, power systems, etc.!

TOPFER 6700N programmable electronic load has sprung up in the market and sells well, for reference.

Encyclopedia is explained like this: the principle of electronic load is to control the internal power MOSFET or crystal leakage of the transistor flux (the size of the duty cycle), relying on the power dissipation of the power of the power tube to consume electric energy equipment, it can accurately detect the load voltage, accurately adjust the load current, and at the same time can realize the simulation of load short circuit, the simulated load is inductive resistance and capacitive, capacitive load current rise time. The debugging and testing of general switching power supply is indispensable.

Personally, I think the following one is a bit more professional:

An electronic load is a type of load that uses electronic components to absorb electrical energy and consume it. The electronic components are generally power semiconductor devices such as power MOS, insulated gate bipolar transistors (IGBTs), etc. Due to the use of power semiconductor devices instead of resistors as the carrier of power consumption, the regulation and control of the load are easy to achieve, and high adjustment accuracy and stability can be achieved.

At the same time, through flexible and diverse regulation and control methods, not only the actual load situation can be simulated, but also some extraordinary load waveforms can be simulated to test the dynamic and transient characteristics of the power supply equipment. This is not possible with load forms such as resistors.

The more famous brands abroad include the United States is Deke Soujing (the original Agilent), Taiwan chroma, Japan chrysanthemum, Shenzhen Sconda, Nanjing Advics. The power supply of Guangdong industrial factories is commonly used chroma and sconda. Huawei, ZTE, Flextronics, etc. use these two brands more.

I haven't seen anything else in the factory.

Electronic loads should have perfect protection functions. The protection function is divided into internal (electronic load) protection function and external (device under test) protection function. Internal protection has:

Over-voltage protection, over-current protection, over-power protection, voltage reversal and over-temperature protection. External protection includes: over-current protection, over-power protection, load voltage and low voltage protection.

When selecting an electronic load, you should choose an electronic load with true protection function. If the functionality is implemented by hardware, the protection will be fast. If it is implemented by software, there is a lag in the speed and the module crashes dangerously.

Due to the special performance of electronic load (providing a powerful test environment to meet different external needs), it occupies a large market in electronic instrumentation, which is mainly suitable for various power supplies, batteries, adapters and occasions that require electronic load testing.

The principle of electronic load is to control the internal power MOSFET or transistor flux (amount of duty cycle), relying on the power dissipation of power of the power tube to consume electric energy equipment, it can accurately detect the load voltage, accurately adjust the load current, and at the same time can realize the simulation load short circuit, the simulated load is inductive resistance and capacitive, capacitive load current rise time. The debugging and testing of general switching power supply is indispensable.

The FT6800A has all the indicators that I have used for this time can meet my requirements, and it is a very good high-power electronic load.

Support military brands.

At that time, when our company purchased, it was Feistech Huang Bin who provided us with the solution, and he personally came to our company to do technical services, which were very professional.
